To (ZZZ whom it may concern.

Be it known that I, JosErH A. GROEBLI, acitizen of the United States,and a resident of the city, county, and State of New York, have inventedcertain new and useful I1nprovements in Jacquard Mechanism, of which thefollowing is a specification.

My invention relates to a jacquard mechanism or automat, and while theremay be other uses for the same, it is of particular advantage in theembroidering art as a means for automatically positioning the tambourframe for the different stitching operations.

My invention relates to what is generally known as an automat orjacquard wherein the various operations which effect the positioning ofthe tambour frame of an em broidering machine are automaticallycontrolled by means of a jacquard card or pattern roll which usuallyconsists of a long strip of paper provided with a number of apertures orperforations, the positions of which on the card, determine the variousoperations of the jacquard and therefore the movements of the tambourframe of the embroidering machine.

The tambour frame must be moved in a great number of differentdirections and eX- tents in order that the stitchingmechanism willproduce thevarious stitches which compose the design, upon the fabric:and in United States Letters Patent No. 528632, dated November 6, 1894,I showed and described in detail a complete jacquard for opisoscillated, or remain stationary if they happen to lie in line with aperforation, as the case may be. Each such needle or feeler is therearranged to operate a definite slide or selector and the slides in turnoperate to select and combine'devices for producing different units ofmotion,,so that the tam- Specification of Letters Patent.

Serial No. 662,277.

bour frame of the embroidering machine will be moved accordin to theresultant of such units of motion, thereby reducing the number of slidesnecessary to produce a great number of movements. In that machine asjust stated, there are 28, feelers or needles for controlling thepositioning movements, in addition to various other needles, and suchneedles are arranged in a horizontal row, laterally of the jacquardcard, and each needle is represented by a position on the jacquard card.The perforations are arranged on the jacquard card in transverse rowsand in each row the perforations may come in line with any of the 28needles just referred to, so that there may be said to be 28, positionson the jacquard card for the positioning needles. In that form ofacquard there are never more than foursuch perforations in a transverserow but those four maycome at any four of the twenty eight positions.The needles and their slides are there arranged in four groups of seveneach and only one in each group is operated at a given operation of themachine, but each of the four perforations may come in any of sevendifferent positions. It will therefore be apparent that in a machine ofthe type referred to the jacquard card must be made wide enough for thetwenty eight slides (when the number of elements are as there shown) inaddition to such slides as are necessary for special purposes, such asfor determining the direction of movement of the tambourframe movingdevices etc. There are in that machine twenty-eight needles controllingthe frame movements and therefore the jacquard card is wide enough tocontrol all of these as well as various special needles.

An important object of my present invention is to make it possible toreduce the lateral dimension of the pattern roll or jacquard card byreducing the number of elements which are directly controlled by thejacquard card bycontact therewith and to so arrange the mechanism thatthe same results may be obtained through this re duced number ofelements. Referring to numbers of elements just for illustration I wouldsay that under my present invention I am able to secure the same resultsby using only twelve needles or feelers, as is obtained by using twentyeight in said patent, reference being had to the needles which determineand combine the units of motion. It will be apparent therefore that thejacquard card may be of less width in order to operate the reducednumber of needles or feelers.

The above is only stated as an instance, the number of parts beingdetermined by the particular jacquard mechanism to which my presentinvention is applied. I accomplish this result by providing a verypositive. mechanism wherein the needles are preferably arranged orconsidered as groups and by causing a number of combinations in eachgroup, the several groups will accomplish the same results as beforewith fewer needles in each group. For instance, let us consider a groupof needles or feelers as consisting of three, there being four suchgroups in a jacquard ofthe type shown in my saidpatent. Each needle in agroup not only controls a given unit of motion, but two or three needlesin a group may be simultaneously operated and their act-ion combinedbefore the selection of the jacquard slides or selectors is effected;For instance, let needle a, represent one unit of motion, needle 6, twounits of motion and needle 0, four units of motion. By operating needlea,'the tambour frame will be moved one unit of mot-ion: by operating 6,two units of'motion; by operating 0, four units of motion: by operatinga and b (and combining their action) three units of motion: by operatinga and c, (and combining their action) five units of motion: by operating5 and c, (and combining their action) six units of motion:

and by operating a, b, and 0, and combining their 'action, seven unitsofmotion. .Thus by using three slides in a group and having themrepresent 1, 2, and 4t units and operatingthem. singly or conjointly,and in the latter case combining their action, I can pro duce the sameresults as where seven were used. in my said patent, each representing adifferent unit, but operated only individually. It is to be understoodthat numbers of parts are here given only as an example and this is truethroughout this case, but it is to be understood that by having'morethan three needles in a group a different number of combinations may besecured.

The above results may be obtained without increasing the number of partsthroughout the jacquard, such as the acquard slides or selectors, forthe above results may be obtained in a jacquard such as is shown in mysaid patent without. changing the number of jacquard slides.

"While my invention is not limited in its application to one form ofjacquarchl profer to simplify the present case by showing my inventionembodied in a jacquard like the one shown in my said patent because itis only necessary to substitute my present mechanism for a small part ofthe mecha nism shown in said patent, the greater portion of which lattermay be here used withmovement of a different extent in a selectingdevice which selects the jacquard slides or selectors'foraction: and anytwo or more dro-ppers in a group may be operated to cause movements inthe selecting device which will be the equivalent of the combined actionof the several droppers so operated. their action singly and combined,and the action of the selecting device which selects the slides, isallaccomplished in a simple and'positive manner and all conflict ispositively avoided. 1

In the drawings forming a partof this application; Figure 1, is alongitudinal section of a jacquard mechanism showing the application ofmy invention, which corresponds with Fig. 5, of my former patent,

Fig. 2, is a diagrammatic view showing the arrangement of acquardslides, and it corresponds with Fig. 43, of my said patent, Fig. 3, isan end elevation of my present mechanism, with parts broken away, and istaken at right angles to Fig. 1, Fig. 4, is a side elevation, Fig. 5, isan elevation of the device for operating the selecting andslideoperating pins, Figs. 6, and 7, are sectional views through themain shaft,-sho-wing cams and levers for operating certain parts of themechanism, and Fig. 8, is a'plan view of a portion of the jacquard card.

' The greater part of my said Patent #528632 may be used in connectionwith my present invention to constitute'a complete jacquard and asthejacquard therein described is the best mechanism known to me for itspurpose, I will describe my present invention as embodied in that formof machine. However, thisis only to simplify the present case, and itwill be apparent- The operation of the droppers,

from the description of my invention that it is not limited to thisparticular adaptation. In order to set forth clearly'a'nd in simple'manner, the nature and working of my present invention it is preferableto refer in some respects to the number of parts in some branches of thedevice but I wish to state that my invention is not limited to astructure having anyparticular number of parts, as the number willdepend partly upon the character of the jacquard to which my in ventionis applied. To make myself more easily understood, therefore, Iwilldescribe my invention asapp'lied to a jacquard like that shown in mysaid patent in which the number of jacquard slides and various otherelements are as there shown. My present invention when applied to such ajacquard construction is substituted for some of the parts of thatconstruction and in other re spects it is supplemental thereof.

In Fig. 1, I have shown many of the parts of the jacquard referred to,but with some parts of my present invention superseding some of theelements of the former construction and a comparison of this view withFig. 5, of said patent will make it apparent that, from the rods whichoperate to couple the various sliding frames down to and including thetambour frame I may, and preferably do, utilize the same elements as areshown in said patent. I have shown in the present case a jacquard fromthe card mechanism to the sliding frames and coupling devices, andconsidering the remainder of the machine as constructed in accordancewith said patent a complete jacquard will be understood therefrom.

l have shown the supplemental shaft 2, (Fig. 1) as provided with thelever 33, wherein movements of varying extents originate; and it is bycombining the various units which originate here, in variouscombinations that the embroidering machine tambour frame may be movedany desired extent or direction. The present invention relates moreparticularly to the devices which perform the functions of selectingthese movements of various extent, determining the direction and thelike.

The lever 3, has connected thereto a number of links 4;, at variouspoints along the lever, so that as the lever is oscillated the linkswill be reciprocateddifferent extents according to the different arcs inwhich the point of connection of the links and lever travel. Each linkis connected with a sliding frame 5, corresponding to the sliding framesG, etc, of my said patent; from which it will be understood that thesliding frames are reciprocated different units in extent, the number ofunits being seven in the example shown.

There are shown the prongs 6 of four sliding frames arranged in ahorizontal plane and these correspond to the frames at to m of my saidpatent and are for the same purpose. From these frames to thetambourframe of the embroidering machine I. preferably utilize the mechanismshown in my said patent. By coupling the several frames 5 with theprongs 6, different combinations of movements are efiected and theprincipal purpose of the card. mechanism and associated parts is toeffect these combinations. The several rods 7, are provided with lookingpins for locking the various frames 5, with prongs 6, so that the latterwill beeper ated according to themovements produced in the former: andthese locking bars and their pins are arranged similar to, and operatethe same as, the locking bars L of said patent and a detaileddescription thereof is not necessary here.

For controlling the interlocking and similar devices 1 preferably employjacquard slides or selectors and preferably arrange them in the sameorder as in said patent, but certain modifications are made in theslides and their operation to adapt them to other branchesofmy-invention as will appear hereinafter.

I will pass to a description of the elements first affected by thejacquard card and follow down to and including the slides.

In Fig. 3, I have shown a pair of rollers or idlers 8, which guide thepattern roll or jacqnardcard, 9, while the latter is traversing thereticulated pattern roller 10. The pat-tern engages around the patternroller 10, and the latter is provided with regularly spaced bars 11,forming intermediate spaces 12 for the entry of the jacquard needles orfeelers while the bars form a backing for the card on each side of therow of needles.

This roller is in all respects like the roller E of my said patent andis intended to be operated in the same manner and by the same mechanismas the roller of my said patent: but the roller in the present case ispreferably arranged in a position at right angles to the roller shown insaid patent. As stated, this roller is operated in the same manner andpreferably by the same devices as in said patent, except as to thedirection of its oscillations. The roller is partially revolved aftereach operation of the machine in the sane manner as in said patent, butas I prefer to have the needles which operate the droppers engage thecard from above I oscillate the card roller up and down instead ofhorizontally. On the main shaft 1, of the machine I havearranged a cam13, in the groove of which travels a bowl 14, on a lever 15 Another arm15 of said lever is connected by the link 15 to the lever 16. The lever16, is fulcrumed on a stud 17, suitably supported. The forward arms 18,on the shaft 17, carry the shaft 19, of the card roller. At eachrevolution of the main shaft the cam 1, oscillates the lever 15 15 andthrough the link 15, arm 16, shaft 17, and arms 18, the card roller ismoved first upwardly and then downwardly.

Above the card roller and arranged above the stopping positions of theslots 12, of the card roller 1 have provided a number of jacquardneedles or feelers which are intended to be engaged by he jacquard cardwhen. the card roller is oscillated, in case the needles are in linewith a part of the card, or to be left in their lower position if theycome opposite an aperture therein. The grouping and arrangement of thesidered as the movement controlling needles.

At the left of each group of movement-controlling needles (relativeposition is only preferable) I have arranged one additional needle 23,24, 26, making four in all. These needles control the directional slidesor those which determine whether the tambour frame moving elements shallbe moved to the right or left as thecase may be. The needles 20, 21, 22,control the extent of movement, and the needles 23, to 26, the directionof movement of the elements which position the tambour frame. There are,therefore, 16 needles in a row for controlling the extent and directionof movement in a jacquard having the same capacity as that shown in mysaid patent and these 16 needles are adapted to produce the same resultsas the 32 needles of the patent.

The several needles are guided in holes in the guide plates 27 arrangedone above the other. Each needle of the movementcont-rolling groups isconnected with a dropper. The needles 20, are each connected by a .thinand flexible strap 28, with a dropper 29, which latter may be consideredas representing one unit of motion in the selecting device. The needle21, is connected also by a thin flexible strap 28, with a dropper 30,arranged behind the dropper 29, and being broader than dropper 29, maybe considered as representing two units of motion in the slide selectingdevice. Also the needle 22, is connected by a thin strap 28, with athird dropper 31, which being wider than both 29, and 30, may beconsidered as representing four units of motion in the slide selectingdevice. As the needles are arranged in a row at right angles to thedroppers, I have offset the straps 28, to bring them to the droppers onebehind the other according to the positions of the droppers. Thisarrangement of droppers is duplicated for each of the four sets ofneedles, making in the instance given twelve droppers in four groups ofthree in each group.

Such a group is shown in Fig. 3. From this it should be understood thatonly the needles controlling the extents of movements of the tambourframe are connected with droppers.

The several groups of droppers lie between the two guide plates 32, and33, so that the droppers may be moved vertically,

and they may also be moved horizontally, but preferably always withinthe confines of these plates. Each group of droppers is further confinedto the proper place by small plates 27 arranged transversely betweentheguide plates 32 and In line with each group of droppers is anengaging element, here shown as rods 34, 35, 36, 37, which reciprocatetoward and from the droppers in apertures 38 in the plate 33.

to draw the several rods 34 to 37 toward their respective groups ofdroppers, independently. To move the reds away from their dropper-s alsoto permit them at the proper time to move against the droppersI haveprovided means which operates simultaneously on their several levers. Ihave provided an arm 48, which fulcrums on a shaft 49, on the plate 44:and beyond the several levers 39 to 42 I have provided .a

lever 50 which fulcrums on a shaft 51. 7 One arm of this lever 50 andthe upper end of arm 48 are united by a link 52 which latter is providedwith the four studs or pins 53,

which project laterally thereof and engage respectively on one side ofeach of theseveral levers 39 to 42, so as to cause the return of theseveral levers in opposition to their several springs. One'arm 54, ofthe lever 50, is connected by a link 55, with an arm of a lever 56,which fulcrums on a stud 57 suitably supported. The other arm of thelever 56, has a bowl 58, which travels in the groove of a cam 13arranged on the main shaft of the machine. At each operation of themachine the cam 13, causes the lever 50,

to be rocked, first to the leftin Fig. 3, to

permit the levers 39 to 42, to be drawn over by their springs 46, andthen to the right to positively return said levers. A

In said Fig. 43, of my said patent I showed, diagrammatically, thearrangement of the various slides, including extent, di rectional andunlocking slides, and in Fig. 2, herein I have shown the arrangement ofslides diagral'nmatically, from which it may be seen that thearrangement is somewhat similar except for the, slides which control.

the unlocking devices and the directional each group, seven of which ato g represent different units of motion and slide h in each group isthe locking slide. There are also four slides E, arranged beyond theabove groups and these control the directional elements. There are stillother slides connected with the above mentioned slides.

by rods 60 each with a slide in group A:

slides b in each of the groups A, B, O, D, are connected each with aslide in group B, slide 0 in each group with a slide in group C, etc.,throughout to slide g. The slides A, B, C, D, E,'F, G, correspond withthe slides Gr to G of my said patent. Be; sides the above there is agroup H of slides 7 containing four i, j, 70, Z, and to each of these isconnected by a rod 60, the slides h, of the groups A, B, C, D. The groupof slides H corresponds with the slides G, of my said patent and controlthe elements which lock the rack frames shown in said patent which arenot to move upon any given operation of the machine. There is stillanother group of slides I containing'four slides, on, n, 0, p, which areconnected by rods 60, with the four slides in group E. These correspondwith slides 1 in my said patent and are adapted to perform the samefunctions as the latter slides, and through the same mechanism. Theycontrol the direction of rotation of the four pinions actuated by therack frames. I

From the aboveit will be apparent that I have provided slides forperforming all the operations performed by the several slides in saidpatent, but I have arranged them differently for convenience except theones marked shuttle, and stopping and they require no change. i It willbe noted that each of the levers 39 to 4L2, is provided with a pin orplunger 61, which are movable laterally of the levers in. transverseholes in the hubs 62*. These pins are arranged to engage the ends of theseveral slides in the groups A, B, C, D, to push the slides. The lever39 has a movement sufficient to cause the pin 61, therein to come inline with any one of the slides in group D. g In similar manner the pin61, on lever/l0, may be brought into line with any slide in group C; pin61, on lever. 41, may be brought into line with any slide in group B;and pin 61, on lever 42, may be brought into line with any slide ingroup A. i have provided means between the levers 39%2 and the severalgroups of slides for guiding the pins '61. I have mounted opposite theends of the several slides a plate 62, which is providedwith as manyapertures 63, as there are slides in groups A to D, and in line withsuch slides.

in said patent Eight of these apertures are arranged in the aretraversed by the pin 61, on lever 39, eight in the arc traversed by thepin on lever 40 and in the same way for the pins on levers il, and 42.These apertures are countersunk at 64, on the side of the plate towardthe levers.

The means for reciprocating the pins 61, is as follows: Each pin 61, hasa grooved engaging head 65, which straddles the Plate 66, and theseheads are adapted to move along the plate 66, and in their respectivearcs. The plate 66, is carried upon arms 67, which are arranged to movethe plate 66, for the purpose of movin the pins 61, toward and away fromtheir several slides. The arms 67 are secured to shafts 68, suitablysupported, and one of them forms part of a lever. The other arm 69 ofthis lever is connected by a link 70, having a slot 71; to a lever 7 3.The latter is fulcrumed upon a suitably supported stud 74, and one armthereof has a bowl 75, which travels in contact with a cam 76, on themain shaft. At each operation of the machine the rise of lever 7 3,permits the spring 77, to draw the arms 67, and plate 66, to the left inFig. l. This causes the pins 61, to contact with and push whichever ofthe slides they are in line with at the time. The return of the pins 61,is caused, positively, by the cam 76, acting on lever 7 3. The needles22, are connected by the rods 23, 24-, 25, 26, with the levers 78, therebeing four such levers arranged side by side and fulcruming on a shaft79. Through these connections the four slides E. shown in Fig. 2 areoperated to control the direction of movement of the rack frames of saidpatent. The upper arms of the levers 7 8, each engage in a slot 80, inthe slides B. (see Fig. 4).

All the slides shown in the right half of Fig. 2 are preferably alike,except that only the slides in group E. have slots for the levers 78.The slides are guided in slots 81, in the four guide plates 82, whichpermit of longitudinal movement only, of the several slides. The slidesare preferably formed of straight plates instead of being T-shapedandeach slide is connected by a rod 60 as previously stated with someslide on the left half of Fig. 2, similar to the arrangement shown insaid patent. On the upper edge of each slide I have provided the twonotches 83 and 84 one just behind the other. On a shaft 85, I havesecured two arms 86, to which is attached a V-shaped bar 87, which isarranged to engage in the notches 83, of those slides which are advancedupon an operation of the jacquard card; and in the notches 84:, of thosewhich are not advanced, but are left in their original position. Aspring 88, connected with the arm 89, and the plate 82, tends to drawthe end 87, of the arm 89, into the notches of the several slides,

slides engage.

while at regular intervals the spring is overi The purpose ofthejp'l'at'es rawsiis, 114.

is to raise tho'se'plates 105, the "slides of i come and the arm isdisengaged from the slides. The arm 89, of lever 86, is connected by alink with a lever 91, which fulcrums on a stud 92. Another arm of lever01, has a bowl 93, which engages with a cam 94., on the main shaft sothat periodically the lever 86, will be rocked to lock and unlock theseveral slides. The arm 80, per; forms a similar function to the arm 0of my said patent.

The slides are preferably only advanced by the pins 61, and returned byseparate mechanism. Levers 95, are mounted on a shaft 96, (see F 4) andto said arms is secured a bar 97, extending across in front of one endof the several slides A, B, C, D, and E. An arm of the lever 95, isconnected by a link 98, with a lever '99, rocking on a stud 100. Thislatter lever has a bowl 101, traveling in a groove in the cam 76-, onthe main shaft. The periodical rocking of lever 95, first to the left inFig. 4, and then to the right, first permits the slidesin Fig. 2, to beadvanced and the lever 95, positively returns all of them upon thereturn movement of the lever. Passing now to the slides shown in theleft in Fig. 1, it will be noted that they are somewhat similar to thecorresponding slides in said patent. On their rear end they are curvedat 103, soas to rock thereon as a fulcrum and are guided by the groovedplates 104. For each of the slides in the left of Fig. 2, there isprovided a plate 'i'vhich plates correspond to, and operate the samemechanisms as the plates is, ofsaid patent. That is, some control therods coupling up movements of different 'extent, others control thedirection of movement and still others control the locking of the rackframes which are not to be moved. Their function andoperation may all beunderstood from said patent.

The several slides last referred to serve to raise the plates 105, orhold them down, as the case may be, and for this reason the plates 105,have pins 106, between which the slides are somewhat modified. There isa recess at 107, on the lower edge of each slide, and a recess 108, onthe upper edge, and behind the first one. To shafts 109 and 110aresecured respectively the arms 111, and 112. On the arms 111, iscarried the plate 113, while on the arms 112, is carried the plate 114,the former being slightly in advance of plate 114, which is a reversalof the condition shown in said patent. To a shaft 115, are secured arms116, which carry a bar or plate 117, which is arranged to engage eitherof the slots 118, in the several plat'es105, for the purpose of lockingthe latter in either their raised or lower positions, and thiscorresponds with the plate M", in said patent.

The forward ends of the which are advanced or moved. to theileftin Fig.'1, for the p'iirpose at opening the as ,1 r

rious locking rods 7, the same as in mysaid Pateiit. Owing to the shapeofthe ends of" these slides and the relative positions'o'f the jaws 113,114, there will be a reversal 'ofth'e action over that of my saidpatent. That is, the slides which remain forward or are not moved areengaged thejlowerj'aw 114,

acting in the reces' s 107 and the upperf'jaw v engagingjon the edge119. The slidesso engaged will be retained in the lower position. Thoseslides which are 'r'eclprocated are, the oneswhich 'c'aiise activemovements and they will be so moved that the aw 114, will engage theslides so moved, at 120, while the upper jaw 118, will'be in line withthe recess 108, and Consequently the slides thus affected will be raised"when the jaws are closed and their respective plates 105, will heraised to operate the locl'iing bars 7,

and associated elements. In ny said patent the slides which remain inthe forward position determine the operation of the machine, or areproperlyfconsi'dered the controlling slides iii each operation, whereasthe present structurethe slides whic'h'are advanced are prere'ramy theones which are he active ones, or control the operation of the lockingeleinehts; and hence the reversal of the shape of the ends of the slidesand the jaws 113, 114. In Fig. 4, I have shown means for rocking shafts109, 110 similar to that. shown in my said patent.

On shafts 109, and 110 areprovided, re

spectiv'ely, the arms 121, 122 and directed in opposite directions fromtheir shafts; and

they are ful'crumed to the bifurcated ends I of a link 123 The lower endof this link connects with a lever 124, which rocks on a fixed stud 125,and an arm of this lever has i a bowl 126, which travels in the grooveof a cam 94 on the main shaft. Each revolution of the cam 94 with themain shaft causesthe lever 124, to rock, and through the link 123, thearms 121, 122, arerocked in reverse directions. I Consequently theshafts 109, and

110 will be rocked and the jawsiia, 114, 7

will move towardand awayfroni each other as they do in my 'sard patent.

On the shaft 115, there is an am. 128,, (see Fig. 4) which is connectedby a link;

129,- with lever 91, rocking from av fixed fulcrum 92. An arm of thisleverhas a bowl 93, that travels in the groove of a cam 94,

on the main shaft, Each 'revoluti0n ofthe cam 94, wlth the main shaftcauses the lever 91, to rock and this, through the link 129,

and arm 128, rocks the shaft 115. As a con sequence the locking bar117,.will disengage from the slots 118, in the L-shaped plates 105, andreenga'ge therewith after the jaws have raised certain ofthe plates.

Operation: It may be first noted that while I have four diiferent groups(in the present instance) of needles engaging the jacquard card havingonly three movement needles in each group as in said patent,nevertheless more than one in each or every group may be simultaneouslyraised by the card, orremain in their lower position because ofperforations in the card, according to the selection of movements. Butwhere more than one in a group is simultaneously raised their action iscombined through the droppers, so that their combined action causes theselection ofa single slide.

A complete operation of the device may be traced as follows: Startingwith. the parts in the positions shown, the card roller will be movedupwardly, so that the jacquard card will contact with certain of theneedles to raise them, while'perforations arranged across the card. willallow certain of the needles to remain in their lower position. Thoseneedles which are raised will move their respective droppers 29, 30, or31, as the case may be, into line with the respective rods 34, to 37,through the action of the flexible straps 28. The lever 50, will then berocked by its operating cam so that the rod 52, and its engagmg pins 53,will be moved to the left in Fig. 3; This will allow the levers 39, 40,41, 42, to be rocked on their shafts by the springs 46, drawing on theseveral arms 45, and as a consequence they may all move to the left inFig. 3. But their movements will not necessarily be the same because therods 34, to 37, will come into contact with the several sets ofdropper-s, and further movement of the levers 39 to 42, will be arrestedby such contact. If .ropper 29, only is in the path of rod 34, lever 39,will rock to its second position and the pin 61, in the hub of thislever will come into line with the end of slide 9, of group D. Ifdropper 30, of the next group is raised into the path of rod 35, by theaction of its needle, then lever 40, will rock until rod 35, comes intocontact with its dropper 30, which will bring pin 61, of lever 40, intoline with slide f, of group C. If dropper 31, in the next group is theonly one raised, lever 41, will rock until rod 36, comes into contactwith said dropper 31, when lever 41, will come to a stop with its pin61, in line with slide (Z,in group B. If droppers 29, and 30 of the nextgroup are both raised rod 37, will contact therewith and lever 42, willcome to rest with its pin 61, in line with slide a, of group A. Ifdropper 30 only in any group is raised such dropper will be moved by therod into contact with the plate 32, before the lever carrying such rodis arrested and the straps 23, are sufficientlyflexible to permit ofthis movement of the dropper. So also if only dropper 31,

of a group is raised it will be moved into contact with plate 32, beforethe lever and rod operating against it are arrested. If both 30 and 31of a group are raised but not 29, then they will be moved until dropper30, contacts with plate 32, and dropper 31, will lie against dropper 30.It will then be apparent that various moveiients in the several levers39 to 42, may be obtained according to the particular droppers in eachgroup which are raised under the action of the jacquard card, and eachlever is individually affected according to its particular droppers. Ifnone of the droppers in a group are raised, the rod 34, 35,, 36, or 37,as the case may be, will be moved until it comes into contact with plate32, and will be arrested by the latter, in which position the levercarrying such rod will come to rest with its pin 61, in line withslide'h, of one of the four groups. Now slide 71., in any group is not amovement controlling slide as its selection is caused by the failure ofa dropper in a group to be raised. Instead slides 71, operate the olevices which lock the rack frames shown in my said patent, and performthe same function as slides G, of my said patent, preferably through therods 7 which correspond with rods is in my said patent, except that whenslides G of my said patent remain in their normal position the rackframes are caused to be locked, while in the present de vice when theslides H are pushed they will cause the rack frames to be locked. Theonly difference in the mechanism necessary to cause this reversal is thechange in the shape of the ends of slides shown in the left of Fig. 1,and in the position of the jaws 113, 114, as previously referred to.Thus if no movement controlling slide in any group is selected foraction the looking slide it in such group will be operated to lock theparticular rack frame which is to be left idle, and the slides h, inthis action operate through the same locking elements as slides G ofsaid-patent.

To revert to the dropper-s. dropper 29, in the group shown in 3, beraised, rod 34, will contact therewith and pin 61, of lever 39, will bein line with slide 9 of group D. If dropper 30, only is raised pin 61,of lever 39, will comeiinto line with slide .f; if droppers 29, and 30are both raised, pin

:61, will come into line with slide 6 of group D; if dropper 31, only israised pin 61,- will come into line with slidecZ; if droppers 29,and.31,-are both raised, pin 61, will come into line with slide 0, ifdroppers 30, and 31, are both raised pin 61, will come into line withslide 5, and if droppers 29, 30, 31, are all raised, pin 61, will comeinto line with slide a. Thus any of'theseven movement slides areselected by the use of three drop- .pers andthree needles to operatethem, and

the slide whichlcauses the locking of a rack levers 67, and the bar 66,carried thereby will be moved laterally of the levers 39 to 42, ortoward the slides-A. B. O. D. This will cause the reciprocation of allfour pins 61', in their hubs and theirends will enter the countersunkapertures 63, in the plate 62, with which they aline, and will be guidedthereby. Further movein'ent of the pins 61, will cause them to engagethe particular slides with which they respectively aline, and cause suchslides to be moved to the left in Fig. 1. Through the connecting rods 60slides in one or more of groups A, B, C, D, etc, with which slides A. B.C. D. are connected will be moved to the left in Fig. 1, but only thoseconnected with those slides A. B. C. D. which were advanced. The slideshaving been selected and moved, the jaws 113, 114, will be moved towardeach other. Those slides which were not moved will be engaged by jaw114, in the recess 107, and at the top edge 119, by jaw 113, and will bethus held in their lower or normal position and their plates 105 willnot operate. But the slides which were advanced will be engaged by thejaw 114, at the point 120, and by jaw 113, in the recess 108, andconsequently when the jaws move toward each other, such slides will beraised. Asthe slides are straddled by the pins 106, their respectiveplates 105, will be raised and the rods 7-, will cause the interlockingof frames 5 and 6 the same as in my said pat- 'ent. Shaft 115, thenrocks and locks the plates 105, whereupon the jaws 113, 114, will beopened again and the slides may be returned to their former position.Shaft 115 will retain the plates locked until just before the jaws closeagain. The operation and purpose of this is the same as the plate lid,of my said patent. At the same time,

or before, the slides A. 13., etc, were moved to the left in Fig. 1,shaft 96, was rocked and moved thebar97, in the same direction to permitthe slides to be so moved. Now that the slides A. have performed theirfunction the plates have been locked and the jaws opened, the shaft 96,will be rocked in a reverse direction by its cam and bar 97 will moveall slides A. 13., etc., which were previously advanced back to theirnormal or starting position ready for another operation. In theoperation described as soon as the bar 87 has locked the slides (Fig. 1)the turned by its cam and the pins 53, on the rod will draw all thelevers 39, to 42, back As soon as or to the right in Fig. 3, and withthem the rods 34, to 37, will be moved to their starting position. Theselevers will now. be ready for a second operation. Preferably upon thereturn of levers -3942 the card roller 10, will be lowered by itsoperating cam and such droppers and needles aswere p'revis ously raisedwill fall back to their lower position to be supported by the plate 27,ready for the next operation. The roller 10, will now be revolvedsufficient to bring another transverse row of perforations under theneedles ready for a succeeding operation. preferably by the mechanismshown in my said patent for revolving'the card roller.

The direction of the movement to be produced by the rack frame on theplanetary gears of my said patent is controlled through needles 22 andtheir direct connection with slides E. There is a directional needle foreach group of movement controlling needles and therefore four in thepresent showing. If in any group of needles a movement is produced uponan operation of the machine and upon the next successive operation amovement is to be produced in the same direction by the same group ofneedles-,there will be a perforation or blank in the card first and notin they second operation a change of direction in a planetary gearoccurs; or conversely, if an. aperture were present in the second andnot in the first a change of direction occurs; if an aperture comesunder needle 22in a'group the needle will remain in itslower positionwhen the card is raised and the rod 23, 24, 25, or 26 (as the case maybe) will remain down; its lever 78, will remain idle and its slide willnot be moved forward. ration appears under such needle 22'; be raisedwith the jacquard card and through its rod it will rock one of thelevers 78. This causes the slides E. with which such lever 78,cooperates to be advanced. As previously stated, the slides E. operateslides '7 V I and the latter preferably are connected with, and operatethe same devices as, the

I prefer to causethe selection to be made in the slides rather than subsequent mechanismsbecause the action 1s slmpler and more positive.
